“…Previous research in other crops with neonicotinoid insecticide seed treatments has suggested the occurrence of non-insecticidal seed treatment benefits. A study of soybean (Glycine max L.) seed treated with thiamethoxam reported accelerated germination and larger seedlings concomitant with buffering against the negative effects of water deficit (Cataneo et al, 2010). A Canadian study on eastern Canadian spring wheat reported that a dual fungicide (difenoconazole and metalaxyl) and an insecticide (thiamethoxam) enhanced the frost tolerance of seedlings (Larsen and Falk, 2013).…”

“…However, the stability responses suggest that performance indicators of a successful crop production system should be broadened. The literature clearly establishes that seedapplied fungicides/insecticides provide benefits (Anonymous, 2009;Buck et al, 2009;Cataneo et al, 2010;Ford et al, 2010) to the plant that extends beyond biotic pressures. Perhaps those same benefits can be realized when the same active ingredients are applied in-crop.…”

Winter Wheat Yields Are Increased by Seed Treatment and Fall‐Applied Fungicide

Poor stand establishment resulting in lower yield is a major constraint to expanding winter wheat (Triticum aestivum L.) land area across the semiarid temperate regions of the northern Great Plains. We conducted a direct-seeded study at nine sites across western Canada totaling 26 environments (site-years) over three growing seasons (2011)(2012)(2013) to observe the responses of the winter wheat cultivar CDC Buteo to fi ve levels of seed treatment (i) Check-no, and (v) dual fungicide/ insecticidal seed treatment: tebuconozole, + metalxyl + imidacloprid; and two levels of fall-applied fungicide (i) Check-no application or (ii) foliar-applied prothioconazole {2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl]-1H-1,2,4-triazole-3-thione} performed in mid-October. Th e check and the fungicide seed treatment, metalaxyl, produced similarly low grain yield resulting in lower net returns, whereas the dual fungicide/insecticide seed treatment provided the highest yield and net returns (CAN+$13 ha -1 ). Fall-applied fungicide improved yield (0.06 Mg ha -1 ), but decreased net returns (-$12 ha -1 ). Plant density increased slightly (13 plants m -2 ) when seed treatments included the insecticide component, imidacloprid. Fall foliar fungicides generally improved spring plant density; however, no benefi t was observed in seed treatments containing imidacloprid. Greater yield and plant stand stability was observed with fall-applied foliar fungicide applications; however, fall foliar would be cost prohibitive. Th e benefi ts of a fall foliar fungicide application requires further exploration in the context of an added input or as an alternative to a spring application as the net returns of a fall foliar compared to no application in the system render the input cost-prohibitive.

“…The use of substances that act as growth regulators may improve seed germination and shoot emergence, particularly in weak or damaged seeds and under adverse conditions, such as temperature extremes or drought, resulting in a stand that is more uniform, vigorous and productive, thereby acting on germination (Cataneo et al 2010). For example, gibberellic acid (GA 3 ) can act as a buffer to maintain good germination along with healthy stand establishment for rice (Lee et al 2012).…”

“…Although many reports describe its insecticidal, plant-protecting properties, just a few investigate its effect on seed germination activities, what may be a key control point in seedling vigor. Its mechanism of action is poorly understood in plants and its stimulus on enzyme activity in the antioxidant system has been documented (Cataneo et al 2010). Other products for treating seeds with an organic composition (polysaccharides, glycoproteins, peptides, fatty acids, amino acids and others), essential to plant growth and development, may have the potential to increase seed vigor by changing nitrogen metabolism.…”

Attenuation of low-temperature stress in rice seedlings

Rice is a cold-sensitive crop, and its exposure to low-temperature stress, during germination and early seedling growth, can negatively affect the initial stand establishment. Substances that act as growth regulators can be used to mitigate this initial stress. Thus, the influence of gibberellic acid, thiamethoxam and a phytohormone was investigated at the growth variables and antioxidant enzyme activity of the 'Irga 424' and 'Puita Inta CL' rice cultivars, at low-temperature (17 ºC). The products act on the germination percentage of 'Puita Inta CL', but vigor is only influenced by giberellic acid. Giberellic acid influences shoot length, irrespective of cultivar, while thiamethoxam and the phytohormone only affect length in 'Puita Inta CL'. The antioxidant activity depends on the cultivar and organ tested (shoot or root). These products mitigate the effects of cold, thereby preventing the formation of reactive-oxygen species and lipid peroxidation, and positively influence the superoxide dismutase enzyme activity.

“…The thiamethoxam is able to model the metabolism of pea, corn and soybeans plants (HORII et al, 2007), to increase beans emergence index (PYNENBURG et al, 2011), stimulate antioxidant enzymes synthesis in soybean seedlings subjected to drought condition (CATANEO et al, 2010) and to boost wheat plants growth (PERELLÓ & DAL BELLO, 2011), metabolism and production (MACEDO & CASTRO, 2011).…”

The product thiametoxam has shown positive effects as increased expression of vigor and biomass formation, raising the photosynthetic rate and formation of deeper roots. The objective of this study was to evaluate the effect of seed treatment with the insecticide thiamethoxam in seeds of U. brizantha cv. Marandu and U. brizantha cv. Xaraés. For this purpose, seeds of the cultivar Marandu and Xaraés which were treated with thiamethoxam bioactivator at doses of zero, 100, 200, 300, 400 and 500 mL 100 kg -1 of seeds. The evaluation of physiological seed quality Urochloa occurred by conducting germination tests, cold test, accelerated aging, seedling length, length of shoot and root length, and emergency field will. The use of thiamethoxam positively affects the physiological seed quality Urochloa. The dose range of thiamethoxam which allowed obtaining the best quality physiological to the two cultivars of Urochloa extends from 230 to 280 mL 100 kg -1 seeds.
